Abstract

The invention provides a lifting mechanism. By adoption of the lifting mechanism, the problems of complex parts, high cost, large space occupation of mechanisms, poor reliability or unavailable automatic changes of engaging force within a certain movement range of gearboxes or pressing elastic pieces in the prior art are solved. According to the lifting mechanism, a single special flexible cantilever gear rack and gears are combined to automatically change the engaging force. The lifting mechanism comprises a flexible cantilever gear rack and a gear set. The flexible cantilever gear rack is made of flexible materials and comprises a fixed end and a gear rack end. Gear rack teeth at the gear rack end are in interference fit with the gear set. The gear set comprises one or N+1 gears. According to the lifting mechanism, as the engaging force can be changed, the purpose of adjusting the front-back moving speed can be achieved, and a gear positioning effect can also be achieved; and meanwhile, the lifting mechanism is safe, capable of preventing collision and suitable for a mechanical driving system which is simple and reliable in structure and has no redundant accommodating space.

Description

technical field [0001] The invention relates to a lifting mechanism, which realizes the function change of the lifting movement through the change of the meshing force generated by the interactive movement of the flexible cantilever tooth row and the gear, and particularly relates to a flexible cantilever tooth row and gear structure with variable meshing force lifting mechanism. Background technique [0002] In the prior art, in order to adjust the meshing force to realize the step-shift function, the technical methods usually adopted include gear box or pressing shrapnel. However, the components of the gear box structure are complicated and costly, and the reliability and durability are limited; although the pressing shrapnel can also change the meshing force, it cannot automatically change the meshing force within a specific range of motion. In the prior art, in order to realize the end point positioning function, the technical methods usually adopted include slots or re...
